Robust FeCoP nanoparticles grown on a rGO-coated Ni foam as an efficient oxygen evolution catalyst for excellent alkaline and seawater electrolysis

Derived from FeCo PBA, the robust FeCoP nanoparticles grown on rGO-coated Ni foam exhibited excellent OER performance. In 1 M KOH and naturally alkaline seawater, the overpotential was only 257 mV and 282 mV at 200 mA cm −2 , respectively.
